Abstract
A casing chisel system includes a two-sided casing chisel and one or more detailed chisels. The two-sided casing chisel has two chisel blades that are mirror images of each other to enable one tool for chiseling and cleaning the doorway casing on either side of the doorway. The two-sided tool simply has to be flipped around to allow cleaning of doorway casing on an opposing side of the doorway. The chisel blades may be coupled to a blade assembly that is detachably attachable to a handle assembly. The blade assembly may have a first end and second end each having a two-sided chisel blade or sanding ends with an abrasive material to allow sanding along a doorway casing. The detail chisel may be straight detail chisel having straight chisel blades or a curved detail chisel having curved chisel blades, that may extend in a radius of curvature.
